Resumen:
Realistic models in Galactic Dynamics seem to present a divided phase space (Giordano & Cincotta (2004)). Therefore, it is necessary to count on efficient techniques to study the global dynamical behaviour in order to split as well as identify the complex nature of the orbital structure. Herein we present some results of an exhaustive comparison between two of such techniques: the well--known Lyapunov characteristic exponents, and a rather new one, introduced by Cincotta & Sim´o (2000), the Mean Exponential Growth factor of Nearby Orbits (MEGNO).
